Not a BL Manhwa

So, the story goes like this, the girl and her gay friend decided to get married so that the gay guy's family will leave him alone(about settling down/tying the not) and they are not TOGETHER! Her friend will give her everything she wants and she'll act as his wife, but the gay guy's brother is really attached to his brother and hates the girl and so over time they get really closer. The girl has brown hair, while the gay guy's brother has a dark blue color. Oh btw, the main leads are the Brown Haired Girl and the Dark blue-haired brother. I forgot to save it, can someone tell me? If you're reading it by chance?
